Overview, Enhanced Recovery, and Reservoir Management Summary LOP production and injection was initiated in October 2018. Lookout development drilling began in March 2018 with six wells completed by year-end 2018. One additional well was drilled in 2019 for a total of seven development wells (three producers and four injectors). Producer MT6-06 was the only fracture-stimulated well. The ongoing development scheme premises water injection with enriched alternating gas injection (EWAG) for pressure maintenance and improved recovery. Gas injection commenced in June 2019 and EWAG cycles continued through 2024. A Lookout geomodel was rebuilt in 2019 based on the data collected while drilling the development wells. Subsequent updates to the geomodel and resulting simulation model continued through 2020 based on observations and learning from dynamic production data as well as data collected from well logging campaigns. These models are used for optimization and to aid in the identification of future development opportunities and will continue to be updated if any new data is collected. Reservoir Voidage Balance and Cumulative Status The tables below summarize average daily injection and production rates, cumulative fluid volumes, and voidage balance as of January 1, 2025. The cumulative I/W ratio at the end of 2024 was 0.90. The following is a summary of the LOP status as of January 1, 2025.

Six pressure surveys were performed in LOP wells during 2024. See Attachment 3 for the 10-412 Report of Reservoir Pressures. Results and Analysis of Production and Injection Log Surveys, Tracer Surveys, Observation Well Surveys, and Special Monitoring There were no injection or production profile logs run in 2024. Review of Production Allocation Factors and Issues In accordance with AOGCC Other Order 112 dated October 12, 2016, Other Order 112A dated December 22, 2016, and BLM Sundry Approval for Measurement by Other Methods dated October 14, 2016, LOP production will receive an allocation factor of one (1.0). Production allocation to individual production wells in the LOP is performed in the same manner as other CPAI North Slope fields. An allocation factor comparing actual total daily LOP production sales to the sum of individual well theoretical rates will be used to adjust theoretical well production to allocated well production. The average individual well allocation factor in 2024 is 0.98. 2024 GMTU Annual Reservoir Review Report 3 Rendezvous Oil Pool Annual Reservoir Review ConocoPhillips Alaska, Inc., (CPAI) as Operator and sole working interest owner of the Greater Mooses Tooth Unit (GMTU), submits this Rendezvous Oil Pool (ROP) Annual Reservoir Review as required by Conservation Order 793, Rule 8. Overview, Enhanced Recovery, and Reservoir Management Summary Rendezvous development drilling began in April 2021 with four wells completed by year-end (two producers and two injectors). ROP production was initiated in November 2021 and injection was initiated in December 2021. Development drilling continued through 2024. In 2024 there were 7 wells drilled (four producers and three injectors) and a total of 24 active wells as of year-end 2024 (12 producers and 12 injectors). The ongoing development scheme premises water injection with enriched alternating gas injection (EWAG) for pressure maintenance and improved recovery. Gas injection began in Q2 2023 with the MT7-11 injector and Q4 2023 with the MT7-94 injector. Cumulative water injection at year-end 2024 was 27.8 MMBW. Cumulative gas injection at year-end 2024 was 38.1 BSCF. A Rendezvous geomodel is continuously being updated as new data is acquired while drilling the development wells. Updates to the geomodel and resulting simulation model will continue based on newly acquired data from drilling, observations, and learnings from dynamic production data, as well as any surveillance data collected. These models are used for forecasting and identifying optimization opportunities. Reservoir Voidage Balance and Cumulative Status The tables below summarize average daily injection and production rates, cumulative fluid volumes, and voidage balance as of January 1, 2025. The cumulative I/W ratio at the end of 2024 was 0.74. Water injection and voidage replacement are primarily impacted by reduced injection rates due to early water breakthrough connections in several injector/producer patterns and excess gas production from the gas-cap. The following is a summary of the ROP status as of January 1, 2025. Rendezvous Oil Pool 2024 Daily Average Rate Cumulative Volume Oil Production 13.5 MBOPD 15.8 MMSTB Gas Production 60.2 MMSCFD 72.1 BSCF Water Production 11.7 MBWPD 8.1 MMSTB Gas Injection 74.5 MMSCFD 38.1 BSCF Water Injection 35.1 MBWPD 27.8 MMSTB 2024 GMTU Annual Reservoir Review Report 4 Rendezvous Oil Pool 2024 Voidage Balance Month Monthly Injection/Withdrawal Ratio, RVB/RVB Cumulative Injection/Withdrawal Ratio, RVB/RVB January 1.37 0.49 February 1.19 0.52 March 1.18 0.55 April 1.41 0.58 May 1.82 0.61 June 1.44 0.63 July 1.48 0.66 August 1.43 0.68 September 1.27 0.69 October 1.12 0.71 November 1.10 0.72 December 1.31 0.74 Reservoir Pressures at Datum Map and Summary and Analysis of Reservoir Pressure Surveys See Attachment 2 for the reservoir pressures at datum map. Twenty-four pressure surveys were performed in ROP wells during 2024. See Attachment 4 for the 10-412 Report of Reservoir Pressures. Results and Analysis of Production and Injection Log Surveys, Tracer Surveys, Observation Well Surveys, and Special Monitoring There were eight production and three injection profile logs run in 2024 to further understand both water and gas entry points along the reservoir laterals. The data continues to be used to understand conformance across the field. To date, temporary downhole plugs and retrievable patches have been used to temporarily isolate sections of the laterals based on profile log results. Additional remediation techniques may be applied in the future. A chemical tracer test was also performed on the MT7-03, MT7-07, MT7-08 and MT7-14A injectors to understand water injection transient time. The test found the initial water interaction time ranges from less than one day to three days. Review of Production Allocation Factors and Issues In accordance with AOGCC Other Order 148 dated December 19, 2018 and BLM Sundry Approval for Oil Measurement by Other Methods and Redundancy Verification of Oil Measurement Secondary Pressure and Temperature Instruments Greater Moose’s Tooth Unit (Rendezvous) dated July 1, 2019, ROP production will receive an allocation factor of one (1.0). Production allocation to individual production wells in the ROP is performed in the same manner as other CPAI North Slope fields. An allocation factor comparing actual total daily ROP production 2024 GMTU Annual Reservoir Review Report 5 sales to the sum of individual well theoretical rates will be used to adjust theoretical well production to allocated well production. The average individual well allocation factor in 2024 is 0.99. 2024 GMTU Annual Reservoir Review Report 6 Attachment 1: Reservoir Pressures at Datum – Lookout Oil Pool 2024 GMTU Annual Reservoir Review Report 7 Attachment 2: Reservoir Pressures at Datum – Rendezvous Oil Pool 2024 GMTU Annual Reservoir Review Report 8 Attachment 3: 10-412 Pressure Survey Results by Pool – Lookout 6.
